What is it?

A superior, economical thermal break and cavity batten solution for residential & commercial builds

With a class-leading R-value of 0.58m² K/W, it is surpassing the National Construction Code’s (NCC) minimum R-value standard of 0.2m² K/W by nearly three times.

Innovative and economical for both timber and steel framing:

  • In steel frame applications, the Cavi-Break Strip excels by creating an enhanced thermal barrier at the interfaces between external cladding and the steel frame.
  • For timber framing, its effectiveness extends beyond thermal insulation. The cavity batten effectively combats condensation, rot, mildew and also boasts fire-retardant properties.

Customer Stories

Coco L Construction

“It was price efficient but also really labour efficient, which should attract many commercial builders on the market. Other products require additional labour during the attachment, such as fiber cement battens, because you have to screw them on and measure and make sure it’s all right.”

Zach Wen, Project Manager

Integrity New Homes Brisbane

“During our trial of the product we utilised the Cavi-Break Strips on the neighbouring build as they were so easy to handle, had great self-adhesive and saved time.”

Brooks Builders

“For us, it’s a no brainer. We’ll definitely be using the ATI Cavi-Strip in more projects. It’s just so simple and easy to use and cost effective, so it’s definitely the product we’ll be using ongoing.”
